On a stormy afternoon, the house is as quiet as ever; on a scorching summer day, the interior is still cool and pleasant; in the hustle and bustle of the city, just a window away is a peaceful private domain - this is no longer a fantasy of future life, but a daily reality brought about by high-end door and window technology in 2026. With the in-depth implementation of national standards such as the "General Technical Conditions for System Doors and Windows" and the continuous upgrading of building energy-saving requirements, the door and window industry is undergoing a profound change from "auxiliary components" to "core building performance". Once a supporting role in the home, it has now become a cutting-edge interface that integrates intelligent interactions, manages building energy consumption, and protects the health of residents. This article will provide an in-depth analysis of three major technological trends and reveal how doors and windows are redefining the quality standards and living experience of modern architecture. 01 From mechanical opening and closing to scene perception In 2026, intelligent doors and windows will have surpassed the basic remote control stage and entered the Scene awareness and autonomous decision-making new era. The core of this transformation lies in the evolution of doors and windows from single functional components to Data nodes integrating environmental sensors . Inside the modern smart door and window frame, millimeter wave radar, temperature and humidity sensors, VOC (volatile organic compounds) monitoring modules and microprocessors work together to build a seven-dimensional environmental perception network. When an abnormal increase in outdoor PM2.5 concentration is detected, the system can automatically shut down and activate the built-in micro-positive pressure fresh air filter within 0.3 seconds; when the indoor carbon dioxide concentration exceeds 1000ppm, the window automatically adjusts the opening and closing angle to introduce fresh air. These smart doors and windows have been deeply integrated into the whole house ecosystem, achieving data interoperability with the building management system (BMS). A voice command of "Start reading mode" can be linked to adjustments: the glass transmittance is reduced to 60%, the indoor light is switched to a 4000K color temperature, and the external noise attenuation is increased to 35dB to create a focused reading environment. This kind of intelligent evolution is not a simple superposition of functions, but the transformation of doors and windows from "static envelope structure" to " Dynamic building interface ” has completely transformed into an intelligent hub that actively manages indoor microclimate, optimizes energy flow, and ensures residential safety. 02 Double leap in materials science and structural mechanics Under the background of the "dual carbon" strategy, building energy-saving standards continue to improve, driving the door and window industry to achieve dual breakthroughs in material innovation and structural design. The technological focus in 2026 has shifted from single insulation performance to Year-round dynamic energy management . material level, Composite vacuum glass Through micro-pillar matrix support and high-performance getter technology, the heat transfer coefficient in the central area is reduced to less than 0.4W/(m²·K). More advanced electrochromic glass uses nano-coating technology to achieve precise regulation of visible light transmittance between 5% and 70%, and dynamically manage solar radiation heat gain. Profile technology has also made significant progress, Multi-cavity composite structure Combined with basalt fiber reinforced materials, the linear heat transfer coefficient is controlled within 0.8W/(m·K). This material not only has excellent thermal insulation properties, but its tensile strength is 1.8 times that of traditional aluminum alloys. Cutting-edge materials research is exploring even more revolutionary possibilities. The phase change energy storage window frame material developed by scientific research institutions can absorb heat during the day and undergo phase change, and release heat at night, achieving Passive thermal energy storage and release .实验数据显示，在典型气候区，此项技术可使建筑供暖能耗降低12-18%。 These innovations not only respond to the urgent need for building energy conservation, but also transform doors and windows from "weak links" in building energy consumption to " Energy management interface ” to promote buildings towards the goal of near-zero energy consumption. 03 Precise adaptation and full-cycle service As the growth rate of the new construction market slows down, the update of existing building window systems has become a new engine for industry growth. This change has promoted the transformation of enterprises from standardized product suppliers to customized products. Customized solution provider. Faced with the challenges of large window size deviations and high structural diversity in old buildings, industry innovators have developed "Measurement-Design-Production" digital closed-loop system .通过三维激光扫描获取窗洞毫米级数据，云端算法自动生成适配方案，柔性生产线进行定制化生产，实现了非标窗洞的高精度匹配。 In response to the special requirements of historical buildings and landscape protection areas, the R&D team created In-situ update technology .在不拆除原有窗框的情况下，将高性能玻璃单元与隔热型材嵌入既有结构，实现性能提升与风貌保护的双重目标，施工过程对建筑使用者的干扰降低75%。 Synchronous innovation of service models, "72 hours silent window rejuvenation" The solution is reshaping industry service standards. The factory-prefabricated modular window system, combined with professional installation technology, controlled the entire process from removal of old windows to performance verification to be completed within three days, greatly reducing residential disturbance. Leading companies have also established Old window material recycling system , to achieve closed-loop resource management: the dismantled glass is processed and converted into building filler; the aluminum profile recycling rate reaches 95%; the sealing material is converted into chemical raw materials through thermal cracking technology. This system not only conforms to the concept of circular economy, but also transforms environmental responsibility into sustainable competitive advantage. When night falls in the city, doors and windows integrated with intelligent systems are adjusting autonomously to optimize the indoor environment; window frames made of innovative materials remain stable amid temperature changes, guarding the boundaries of building energy consumption; and windows in old buildings that have undergone renewal are extending the life of the building with new performance. The transformation of doors and windows is essentially a redefinition of the relationship between architecture and nature and the relationship between architecture and human settlement needs. From isolation to interaction, from energy consumption to energy saving, from standardization to personalization - behind this technological evolution is the unremitting pursuit of a higher quality living environment. A window is not only a component of the building, but also a smart interface connecting people and the environment, present and future.

Wisdom starts a new chapter and builds the future At the beginning of 2026, the National Working Conference on Housing and Urban-Rural Construction clearly listed “orderly promotion of the construction of ‘good houses’” as an annual key task, and green buildings and intelligent upgrades have become the core orientation of industry development. As the core carrier of the building envelope system, the intelligent system doors, windows and curtain wall industry are ushering in unprecedented structural changes. The triple force of policy drive, technology iteration and market demand has promoted the industry's transition from "product competition" to "system solution competition" and the evolution from single functional components to building smart ecological nodes. This article will provide an in-depth analysis of the four far-reaching changes in the industry in early 2026, and gain insight into the future development of building envelope systems. 1. Strong policy constraints make green energy conservation a hard threshold In 2026, the mandatory power of green building-related standards will be fully released, setting an insurmountable green bottom line for the intelligent system doors, windows and curtain wall industry. The national standard "Green Building Evaluation Standards" (2024 Edition), which will be implemented on October 1, 2024, clearly requires that all new buildings from 2025 onwards will meet basic green standards, star-rated green residences will become an encouraged direction, and green buildings will officially change from "optional" to "rigidly required". This policy orientation directly promotes a significant increase in the energy-saving performance standards of doors, windows and curtain walls. The new version of the "General Specifications for Building Energy Saving and Renewable Energy Utilization" requires that the thermal performance standards of curtain walls be increased by 20%. Forced by policies, the industry has seen two significant changes: First, the Labeling and transparency of performance parameters . Core performance parameters such as thermal insulation (K value), sound insulation (Rw value), and air tightness (AP) of doors and windows have become the core basis for consumer decision-making just like the energy efficiency labels of home appliances. Leading companies have launched "zero carbon series" products with a heat transfer coefficient (Uw value) of the whole window stabilized below 0.8 W/(m²·K) to meet the needs of passive buildings; secondly, In-depth intervention of green financial mechanism , high-performance energy-saving doors, windows and curtain wall projects can enjoy policy preferences such as green credit and green bonds, and the "green premium" market mechanism has gradually formed to promote the industry to get rid of the traditional path dependence on high energy consumption and high emissions. At the same time, the existing building energy-saving renovation market is accelerating, and the renovation market capacity in the curtain wall field alone will exceed 80 billion yuan, bringing new incremental space to the industry. 2. AI Internet of Things, moving towards active intelligence In 2026, the "intelligence" of intelligent system doors, windows and curtain walls has bid farewell to the simple remote control stage and entered the era of active intelligent ecology with AI algorithms as the core. The fourth-generation smart door and window system accelerates iteration. By integrating environment sensing modules, edge computing and 5G communication technology, it realizes full-link autonomous operation from "perception-decision-execution" and becomes the "smart skin" of the building. At the level of technology implementation, two major innovation directions are particularly prominent: First, Popularization of AI environment housekeeping system . The doors and windows have built-in multispectral sensors and millimeter-wave radars, which can monitor seven environmental indicators such as indoor and outdoor PM2.5, CO₂ concentration, temperature and humidity, and noise in real time. The algorithm automatically adjusts the opening and closing angles and links the fresh air system to achieve a dynamic balance of health and energy saving. Some high-end products also integrate active noise reduction (ANC) technology to accurately neutralize low-frequency traffic noise; secondly, Security protection automation . The in-depth application of millimeter-wave radar technology allows doors and windows to accurately identify abnormal loitering in front of the window. Through low-light warning and linkage alarm with the householder's App, passive protection is upgraded to active early warning, and the false trigger rate is reduced to an industry low of 0.8%. It is worth noting that the full implementation of the Ministry of Housing and Urban-Rural Development’s “Smart Residential Construction Guidelines” promotes the deep integration of smart doors and windows with building automation systems and whole-house smart platforms. It is expected that by 2030, the smart door and window configuration rate of new residential buildings will be mandatory to reach 100%. 3. Digital reshaping, whole-chain efficiency revolution Digital technology is profoundly reconstructing the production and service logic of the intelligent system doors, windows and curtain wall industry. The integrated application of BIM forward design, modular prefabrication and digital twin technology is promoting the transformation of the industry from "traditional construction" to "digital intelligent manufacturing", and the efficiency of the entire industry chain has achieved a qualitative leap. In the front-end design process, the application rate of BIM technology continues to increase. It is expected that the proportion of BIM applications in high-end projects in East China will reach 78% in 2026 , through parametric design, it can accurately adapt to the needs of complex scenes such as special-shaped curved curtain walls, and the design error rate is reduced by more than 90%. On the manufacturing side, the intelligent closed-loop manufacturing of the entire industry chain has become the core competitiveness of leading companies. The entire process from high-precision aluminum extrusion, glass deep processing to complete spraying is fully self-controlled and coordinated with QR code traceability throughout the production process to ensure delivery accuracy and consistency. At the same time, the flexible production line shortens the delivery cycle of non-standard customized products to 60% of the industry average. In the construction and operation and maintenance aspects, modular installation technology shortens the construction cycle by 30%, and the application of digital twin technology enables visual operation and maintenance of the entire life cycle of the curtain wall. By monitoring structural deformation and energy consumption data in real time, faults can be predicted in advance and maintenance plans can be formulated, reducing the whole life cycle cost by 19%. 4. Restructure the landscape and shift to full-chain services In 2026, the competition in the intelligent system doors, windows and curtain wall industry has upgraded from a single product performance competition to a " Products Services Full Lifecycle Solutions "Competition of comprehensive strength, industry concentration has accelerated, and the brand landscape has been reshaped. On the one hand, leading companies are accelerating their transformation into full-industry chain service providers, forming integrated service capabilities of "design-production-construction-operation and maintenance" through vertical integration, and occupying a dominant position in high-end fields such as large-scale landmark projects, hospitals, and schools. The industry's CR10 concentration is expected to increase from 28% in 2025 to 35% in 2030. On the other hand, there is an obvious trend of specialization in the segmented tracks, and differentiated competition among enterprises is intensifying: some focus on the passive building field and become the core supplier of PHI certification projects; some are deeply involved in the field of high-end art doors and windows, creating spatial artworks through cross-border cooperation with architectural masters; some are positioning themselves as "national performance windows" and realizing universal benefits of high-performance products through large-scale intelligent manufacturing. At the same time, service delivery has become the industry standard. The integrated service system of "measurement, installation, and maintenance" has replaced pure product sales. The standardization of installation processes and the worker certification system have become new competition barriers for brands. Use the power of change to build a high-quality architectural future At the beginning of 2026, the intelligent system doors, windows and curtain wall industry is at the intersection of triple changes driven by policy, technological innovation and market upgrading. Greening is the foundation for development, intelligence is the core driving force, digitalization is the support for efficiency, and service-oriented is the value orientation. , the four major changes jointly pushed the industry to bid farewell to the old path of "mass construction and mass consumption" and enter a new era of high-quality development. For industry participants, only by closely following policy guidance, deeply cultivating technological innovation, and embracing digital transformation can they take the lead in the reconstructed market landscape. For consumers and the construction industry, this change will bring more energy-saving, smarter, and safer building spaces, inject core momentum into the construction of “good houses”, and ultimately achieve a win-win situation between residential quality and green development.

The cold air has suddenly hit these days, and have you ever had such a "shock moment" in the midst of rain and snow - forgetting to close the window when you go out in a hurry, and when you come home and open the door, your heart feels cold: water accumulates on the window sill, the floor is soaked, there are water marks on the wall, and even mildew has quietly grown on the corner of the wall... Water seepage, mold, furniture damage...a single oversight may cost thousands of dollars to repair, not to mention the potential threat to the health of your family due to mold. Door and window management in winter has become a "sweet burden" for many families. But now, that can all change. 1. Know the weather better than you and act earlier than you Picture this: you are in the office concentrating on work, and sleet starts to fall quietly outside the window. And the windows of your home, the first time the rain or snow touches the glass, they have closed automatically and quietly, making a perfect seal. When you get home, the house is still dry and comfortable, with only a warm reminder on your phone: "At 3:22 pm, rain and snow were detected, and the east side living room window has been automatically closed." This is not a science fiction scenario, but equipped with " winter guardian mode "Smart doors and windows are being used daily in countless families. 2. What exactly is the “black technology” behind this? Precision environmental sensing system Smart doors and windows are equipped with highly sensitive rain and snow sensor , like installing "weather antennae" on the house. It does not rely on the "regional coverage" of weather forecasts, but directly monitors the real environmental changes outside the window. It can complete the identification of rain and snow the moment they contact the glass, realizing Millimeter response . Intelligent linkage logic algorithm The system doesn’t simply “close the window”—it comprehensively determines: ● Is it a brief drizzle or a continuous heavy rain? ● How strong is the wind outside? Does the seal need to be strengthened? ● Will the temperature difference between indoor and outdoor cause condensation? ● Do I need to start the dehumidification mode simultaneously? Multiple protection mechanisms ●Level 1 protection: Rain and snow sensor triggers → window automatically closes ● Secondary protection: The humidity sensor detects an increase in humidity near the window → strengthen the sealing strip pressure ● Level three protection: Abnormal weather warnings are synchronized to mobile phones → remote confirmation and manual control of permissions 3. It is a comprehensive winter home protection ● Actively prevent condensation: When the intelligent system detects that excessive indoor and outdoor temperature differences and high humidity may cause condensation on the glass, it will automatically adjust the indoor micro-ventilation to maintain a temperature balance on the glass surface and prevent the formation of condensation water from the source. ● Intelligent humidity management: Linked with air conditioners and dehumidifiers, when the indoor humidity is detected to be too high (the critical point for mildew is 60%RH), the dehumidification equipment will be automatically started to keep the humidity within a healthy range of 40%-50%. ● Remote warning and control: Even if you are thousands of miles away, you can check the status of doors and windows in real time through the mobile phone APP, receive weather warnings, and manually intervene at any time - true "all-weather protection." Let technology integrate into life and let care be guarded silently A true smart home is not a collection of fancy features, but something that has already been considered for you before you need it. Doors and windows, as the "outerwear" of the home, act as the first line of defense to protect warmth and dryness in winter. The "winter guard mode" of smart doors and windows uses technology to make up for our occasional negligence, transforming uncertain weather factors into certain peace of mind. It makes home not only a physical space, but also a "living body" that knows how to take care of itself. This winter, let smart doors and windows become the climate guardians of your home, completely blocking moisture and mold outside the windows. When you go home, you are always warm and dry.

In 2025, China's doors and windows industry will officially enter the trillion-dollar market track. In this blue ocean full of opportunities, system doors and windows bucked the trend with an annual growth rate of 35%, far exceeding the industry average growth level of 6.5%, and has become the "darling" supported by many national policies. While traditional doors and windows are still stuck in the quagmire of homogeneous price wars, why can intelligent system windows gain policy favor and lead industry changes? Behind this is the inevitable convergence of dual carbon goals, people's livelihood upgrades and industrial transformation. Release of policy dividends: enabling system window growth Policy guidance at the national level has always been the "baton" for industrial development. In recent years, from the State Council to local governments, a series of policies focusing on building energy conservation, green development, and smart homes have been intensively introduced, establishing a complete policy support system for the rise of smart system windows. .Driven at the core of the dual carbon goals, "2024-2025 Energy Saving and Carbon Reduction Action Plan" It is clearly proposed to implement the promotion of energy-saving doors and windows, requiring that the energy-saving renovation area of existing buildings be completed by the end of 2025 by more than 200 million square meters compared with 2023, and the energy-saving rate of residential buildings after renovation is increased by 30%. And " Implementation Plan for Carbon Peaking in Urban and Rural Construction Sector" More directly link the energy-saving performance of doors and windows to building energy consumption, require new urban buildings to fully implement green building standards in 2025, and promote the application of high-performance energy-saving doors and windows. These policies have directly raised the entry threshold for the door and window industry in terms of energy consumption standards and renovation tasks. Intelligent system windows have become the core carrier of policy implementation due to their excellent energy-saving performance. At the same time, the promotion of large-scale equipment updates and trade-in of consumer goods has further activated existing market demand. Relevant action plans issued by the State Council Clearly consider doors and windows as the focus of energy-saving renovation of existing buildings , Shanghai, Jiangsu and other local governments have issued specific plans. Shanghai alone plans to promote energy-saving renovation of 32 million square meters of existing buildings, focusing on promoting energy-saving doors and windows. In addition, policies such as the "Beijing Special Action Plan to Deepen Reforms and Boost Consumption" encourage the promotion of smart home products and provide policy endorsement for the scenario-based application of smart system windows. Technical core adaptation: natural fit with policy requirements The favor of policies never comes out of thin air. The technical advantages of intelligent system windows make it the best choice to meet policy requirements. In building energy consumption, heat loss related to doors and windows accounts for up to 30%, and intelligent system windows have fundamentally solved the pain points of this industry through technological innovation. In terms of energy-saving performance, intelligent system windows have surpassed traditional doors and windows in all aspects. Current policies require that the heat transfer coefficient of doors and windows must be controlled below 1.5W/(㎡·K). However, through the integrated application of technologies such as LowE glass, broken bridge aluminum profiles, and polyurethane foam filling, mainstream intelligent system windows can have a heat transfer coefficient as low as 1.2W/(㎡·K) or below, and some high-end products can even reach 0.8W/(㎡·K). Data shows that compared with traditional doors and windows, smart system windows can reduce a household's electricity consumption by 30% to 40%, which is in line with the core goal of building energy conservation and carbon reduction. The intelligent upgrade allows it to achieve a leap from "passive protection" to "active management". A smart system window developed by a company has built-in gas sensors, wind and rain sensors and other modules. It can respond to gas leaks within 3 seconds and automatically open the window for ventilation. It will automatically close in case of wind and rain. With functions such as voice control and face recognition, it builds a comprehensive home security defense line. This smart closed loop of "sense-response-control" not only improves living comfort, but is also in line with the policy-driven development direction of "whole-house smart IoT" and has become an important entrance to the smart home ecosystem. At the level of green manufacturing, the intelligent system window industry chain also fully responds to policy calls. The policy requires the door and window industry to increase the proportion of recycled materials. In 2024, the proportion of recycled zinc in the field of door and window accessories has exceeded 35%, and it is expected to increase to more than 45% in 2025. By promoting flexible production lines and digital twin technology, leading companies have reduced unit production costs by 18.7% and controlled product defect rates to 0.32%, achieving a win-win situation between economic and environmental benefits. Trillion market opportunities: demand and policy fit Policy guidance must ultimately be based on market demand. The high growth of smart system windows is essentially a two-way fit between policy guidance and consumption upgrades. China's doors and windows market size has exceeded 1.1 trillion yuan in 2025 , among which the existing housing renovation market is expected to reach 230 billion yuan, with an annual growth rate of 15%. This market has become an important growth pole for intelligent system windows. With the upgrading of consumption concepts, consumers' demand for doors and windows has shifted from simple protection from wind and rain to a comprehensive experience of health, energy saving, and intelligence. The "2025 Green Doors and Windows Consumption White Paper" shows that more than 80% of consumers regard energy-saving performance as the primary purchase indicator, and the focus on intelligent functions has increased by 38% year-on-year. In the high-end residential market, the area of ​​new high-end commercial residential buildings nationwide will exceed 320 million square meters in 2025, a year-on-year increase of 9.7%. The demand for smart system windows in these projects has reached 32.7%. The differentiated demands of regional markets further confirm this trend. The demand for system windows in East China accounts for 38.6%, and the penetration rate of system windows in Guangdong Province has exceeded 35%; in North China, with the growth of residential area in Beijing, Tianjin and Hebei, the market potential continues to be released. The precise matching of regional implementation of policies and market demand has formed a global growth pattern for intelligent system windows. From the intensive release of policy dividends, to the precise adaptation of the technology core, to the rigid support of market demand, the 35% high growth of intelligent system windows is no accident. Behind its becoming the "darling" of the policy is the practice of the concept of green development, and it is also a response to the upgrading of people's livelihood quality. Looking to the future, with the further support for green building materials and smart home industry chains from policies such as the Catalog of Industries to Encourage Foreign Investment (2025 Edition), as well as the implementation of the carbon footprint certification system, the market penetration rate of smart system windows will increase from the current 21% to 35%, and the proportion of green energy-saving products will exceed 65%. Driven by both policies and markets, smart system windows will not only reshape the competitive landscape of the doors and windows industry, but also become the core force in driving the carbon peak in the construction sector and achieving high-quality living.

When “good houses” become the core orientation of national housing development, the green upgrade of building envelopes reaches a critical juncture. In 2025, the "Energy Efficiency Limit Standard for Green Manufacturing of Building Curtain Walls" (GB 38456-2025) was officially implemented. This mandatory standard, which is called the "most stringent in history" in the industry, uses clear energy efficiency indicators and process red lines to delineate a hard boundary for green development for the curtain wall industry. It also opens a new chapter in the transformation of building curtain walls from "scale expansion" to "value creation". Standards Breaking: Anchoring the “Double Carbon” Energy Efficiency Revolution Driven by the dual drive of the "dual carbon" strategy and the upgrade of building quality, the introduction of GB 38456-2025 is no accident. The Ministry of Housing and Urban-Rural Development has clearly stated that a "good house" must have four attributes: safety, comfort, greenness, and intelligence. As the core component of the building's skin, the curtain wall's energy consumption level directly affects the overall energy-saving effect of the building. The core breakthrough of this standard is to transform green manufacturing from "advocative requirements" to "mandatory constraints", which directly addresses the industry's pain points of high energy consumption and high emissions. Two key quantitative indicators in the standard set clear entry thresholds for the industry: ● Energy consumption hard indicators: The energy consumption of aluminum profile surface treatment is ≤0.85kWh/m². This value is about 30% lower than the average energy consumption of traditional processes, which means that companies must achieve a qualitative leap in energy efficiency through technological upgrading. Compared with the GB 21351-2008 standard widely adopted by the industry before, the new indicators focus more on the core production links of curtain walls, significantly improving the accuracy of energy efficiency control. ● Emission strict red line: VOCs emission ≤20mg/m³. This standard is in line with the ultra-clean emission requirements of the petrochemical industry and will promote curtain wall production from "end treatment" to "source control". It should be known that VOCs emissions from traditional solvent-based spraying processes often far exceed this value. This indicator will accelerate the popularization and penetration of environmentally friendly processes. Say goodbye to chromate and embrace new green technology If energy efficiency indicators are "quantitative constraints", then process innovation is a "qualitative breakthrough". GB 38456-2025 clearly states that " Compulsory elimination of chromate passivation process and comprehensive promotion of chromium-free pre-treatment technology ”, this requirement will completely change the industry ecology of aluminum profile surface treatment. The chromate passivation process has been widely used due to its low cost and good protection. However, hexavalent chromium, as a known carcinogen, not only poses a serious threat to the health of operators, but improper wastewater treatment can also cause lasting environmental pollution. The chromium-free pretreatment technology uses zinc, molybdenum, titanium and other environmentally friendly ingredients to replace chromate, which completely eliminates the risk of chromium pollution while achieving the same anti-corrosion performance. It has accumulated mature application experience in the fields of automobiles and high-end building materials. In terms of spraying technology, standard Focus on promoting the popularization of environmentally friendly processes such as powder spraying . Traditional powder spraying requires curing at around 200°C for 10-13 minutes, but new low-temperature fast-curing powder coatings (such as Defuson 09 system) can reduce the curing temperature to 160-180°C, shorten the time to 6-10 minutes, reduce natural gas consumption by 25%-30%, and increase production efficiency by more than 30%. What is more noteworthy is that this type of environmentally friendly process does not require large-scale modifications to existing equipment and can achieve compliance only through parameter adjustment, reducing transformation costs for enterprises. Compliers survive, innovators win The mandatory implementation of standards will inevitably lead to the restructuring of the industry structure. For enterprises, this is both a challenge and an opportunity. In the short term, small, medium and micro enterprises may face pressure to upgrade technology, but if they can seize the transformation window, they will achieve a leap-forward improvement in competitiveness. Combining policy guidance and technological trends, enterprises can make efforts in three aspects: ● Technical path upgrade: Priority is given to the combined process of "chrome-free pre-treatment and low-temperature powder spraying". ● Whole-process energy efficiency management and control: Establish an energy efficiency accounting system from raw material procurement to finished product delivery. We can learn from the experience of "production process energy efficiency classification" in the electrode foil industry, break down the energy consumption indicators into each production link, and achieve precise energy saving through intelligent monitoring. ● Leverage policy dividends: At present, governments in many places have introduced policies to support green building materials, such as providing floor area ratio incentives to projects using ultra-low energy consumption processes and expanding the scope of green building materials procurement subsidies. Enterprises should actively align with policies and reduce transformation pressure by participating in demonstration projects and applying for green credit. Green curtain walls make buildings more beautiful The implementation of GB 38456-2025 marks that my country's building curtain wall industry has officially entered the era of "green hard constraints". This is not only a standard for the production process, but also the implementation of the concept of "good house" - when the curtain wall is no longer just the "coat" of the building, but a "green barrier" with energy saving, environmental protection and safety attributes, the quality connotation of the building can truly be realized. For the industry, this change is both a challenge and an opportunity. Eliminating backward production capacity and promoting green technology will promote the transformation of the curtain wall industry to high-quality development and lay the foundation for emerging fields such as building photovoltaic integration and smart curtain walls. With the in-depth implementation of the standards, a group of companies with leading technologies and advanced concepts will stand out and lead the industry to realize the beautiful vision of "homes are better for everyone".

In the 2025 Double Eleven home consumption list, young people's shopping carts are undergoing obvious changes - cosmetics are giving way to smart home appliances, fashionable shoes are replaced by energy-saving building materials, and the sales of home appliances have exceeded 22%. When "upgrading your home" has become a new consumption theme, the pain points of traditional doors and windows have become more prominent: air conditioning costs remain high on hot days, and the air in confined spaces is turbid; when you live alone, you are always worried about abnormalities outside the door, and traditional security false alarms continue; you want to respond to the "double carbon" call, but you can't find practical energy-saving solutions. The black technology of smart doors and windows that will emerge in 2025 is accurately solving these problems. National policies have already sent signals to encourage the electrification and digital transformation of traditional building materials such as doors and windows. Nowadays, the single attribute of traditional doors and windows of "shielding from wind and rain" has been subverted, and the new generation of intelligent system doors and windows have evolved into "active service stewards". The concentrated explosion of the three core technologies in 2025 will completely transform doors and windows into home core terminals that understand the environment, protect safety, and generate electricity. Dynamic Adaptation: Intelligent Microclimate Adjustment Who doesn’t want the temperature at home to be always comfortable and the air to be fresh? The dynamic environment adaptive technology of 2025 will allow doors and windows to become accurately controlled "microclimate regulators", saying goodbye to the rigid experience of fixed modes. Its core secret is ternary sensing matrix ——Temperature, PM2.5, and air flow sensors capture indoor and outdoor environmental data in real time, and with the edge computing module, decisions can be made and operations executed within 0.3 seconds. When the indoor carbon dioxide concentration is higher than 1000ppm ("Indoor Air Quality Standard" GB/T 18883-2022 recommended warning threshold), the doors and windows will automatically turn on the top-hung ventilation mode to ensure air circulation and avoid direct cold wind blowing; once an unexpected sandstorm or heavy rain is detected outdoors, the sealing strip will pass through the electrorheological technology The technology hardens instantly, and the sealing level jumps from IP54 (dustproof level 5, waterproof level 4, can prevent splashing water) to IP68 (dustproof level 6, waterproof level 8, can be immersed in water for a long time under specified pressure), even fine sand and dust can be seamlessly penetrated. According to authoritative testing data in the field of building energy conservation, this type of smart doors and windows can Reduce air conditioning load by 25%-30% in summer, reduce heating energy consumption by 20%-25% in winter, and control indoor temperature fluctuations within ±1.5°C. . For families with elderly people, children or sensitive people at home, this stable living environment is undoubtedly a healthy "invisible shield". The use of foamed composite strips that expand when exposed to water combined with multiple sealing processes can further improve the air and water tightness of doors and windows, effectively cope with extreme weather such as typhoons and rains, and comply with the national standard "Grading and Testing Methods for Wind Pressure Resistance of Building Doors and Windows". Biological protection: 360° safety protection Home security is always the bottom line, smart doors and windows in 2025 have Upgrade protection from "lock" to "whole system protection" , using multi-modal biometric technology to weave a 360° safety net with no blind spots. The millimeter-wave radar built into the door and window profile is the "first sentry". When someone approaches within 1.5 meters, the system will immediately start triple biometric verification: the iris scanning matching degree must reach more than 99.5% (mainstream high-precision equipment parameters in the industry), the gait analysis cycle error does not exceed ±0.3 seconds, and the voiceprint recognition frequency covers 300-3400Hz (the audible range of the human ear and the core frequency band of speech). This "multi-dimensional cross-validation" completely eliminates security vulnerabilities such as fingerprint copying and password cracking. In case of abnormal situations such as violent window breaking, the three-level protection mechanism will be activated instantly: In the first step, the glass surface forms an ion protective layer through electrostatic induction, and the hardness increases by 30%-40%; in the second step, the polycarbonate interlayer automatically expands to prevent glass fragments from flying and hurting people; in the third step, the frame releases an instantaneous voltage of 3000V (current Energy recovery: doors and windows turn into power stations Driven by the "dual carbon" policy, smart doors and windows in 2025 have become household "micro power stations" that can be self-sufficient and make money by selling electricity. At the core of all this is a breakthrough in cadmium telluride thin-film solar cell technology. By integrating cadmium telluride thin-film cells in insulating glass, doors and windows can generate electricity while maintaining a light transmittance of over 80%. Currently, the photoelectric conversion efficiency of mass-produced components of this type of cells has exceeded 17%, with the highest efficiency in the laboratory reaching 21.28%, and it can still generate electricity stably in low-light environments. The vanadium flow battery built into the window frame is responsible for energy storage and can store 60% of the power generated. It has a cycle life of more than 20,000 times and a designed service life of 20-25 years, fully meeting the daily needs of families. From "passive defense" to "active service", from "energy consumption" to "energy production", the evolution of intelligent system doors and windows is essentially an upgrade of the living concept. Data from the China Construction Metal Structure Association shows that the market penetration rate of high-end doors and windows will reach 75% in 2025, an increase of 38 percentage points from 2020. Choosing an intelligent system window is not only buying a product, but also introducing a new one to your home. Active environment manager . It works silently, optimizing light, air, temperature and sound, returning the energy originally used to resist changes in the outside world to life itself. When technology is invisible, comfort happens naturally ——This is perhaps the most profound change that intelligent system doors and windows have brought to us.

When the "double carbon" strategy is deeply implemented and the "good house" policy is clearly guided, the intelligent system doors, windows and curtain wall industry is ushering in a critical turning point from scale expansion to quality leap. From November 20 to 22, 2025, the CWE China (Beijing) International System Doors, Windows and Curtain Wall Expo was grandly opened in Beijing. With "creating the most influential building integrated solution platform in Asia-Pacific" as the core, it brings together the industry's cutting-edge technologies, benchmark companies and innovative ideas to inject strong impetus into the development of the industry. Industry trends: two-wheel drive of policy and market Currently, China's smart doors, windows and curtain wall industry is in a period of dual benefit from policy dividends and market demand. Data show that the industry market size has exceeded 680 billion yuan in 2024, and is expected to climb to 1.1 trillion yuan in 2030, with an average annual compound growth rate maintained at around 8.2%. Behind this growth is the collaborative promotion of multiple factors: ● Policy level , the "14th Five-Year Plan for Building Energy Saving and Green Building Development Plan" and "Near-Zero Energy Consumption Building Technical Standards" and other regulations have been intensively introduced, requiring that new urban buildings in 2025 fully implement green building standards, with star-rated green buildings accounting for more than 30%, directly promoting the transformation of doors, windows and curtain walls to high performance, low energy consumption and recyclability. ● Market demand side , urban renewal, energy-saving renovation of old buildings, construction of super-high-rise public buildings and other projects continue to release incremental growth.

Under the dual empowerment of policy guidance and technological innovation, the intelligent system doors, windows and curtain wall industry will surely move forward steadily on the road of high-quality development, writing a new chapter for the realization of the "double carbon" goal and the upgrading of the construction industry.

Technology empowers warm winter/defines a new paradigm of winter residential energy conservation The north wind is biting and the chill is getting thicker. Whenever winter comes, we always hope that our home will be a warm and spring haven. However, have you ever felt that even if the heating is fully turned on, cold air still penetrates into the room and the temperature cannot last? Traditional doors and windows often become the "short board" of home insulation, silently wasting energy and warmth. Today, we will discuss in depth how to build an indestructible "temperature barrier" through intelligent system doors and windows to scientifically improve the quality of winter living. 1. Concept upgrade: from “sheltering from wind and rain” to “smart constant temperature” In the process of home furnishing evolution, our expectations for doors and windows have long gone beyond basic protection from wind and rain. Today, when modern architectural aesthetics and smart life attach equal importance to each other, the role of doors and windows is being redefined: ● It should be a "stabilizer" of temperature, not a "weak point": We pursue a constant and uniform indoor temperature, rather than overheating near the heating device or freezing near the window. ● It should be a "manager" of energy rather than a "source of waste": We hope to reduce unnecessary heat loss, so that every energy consumed creates effective comfort value, rather than disappearing quietly through the gaps in doors and windows. ● It should be the "guardian" of comfort, not the "source of problems": We hope to enjoy bright lighting without having to endure condensation on the glass surface, ensuring a dry and healthy home environment. This cognitive transformation from passive protection to active adjustment is the core mission of intelligent system door and window technology. 2. Core analysis: The core of thermal insulation technology for intelligent system doors and windows Intelligent system doors and windows are a complete set of performance-oriented technical solutions. Its winter insulation capabilities stem from systematic innovations in materials, structures, sealing and intelligent control. Structural innovation: multi-cavity broken bridge profile High-strength aluminum alloy is used, and high-strength insulation strips are injected into the middle of the profile to form an effective "broken bridge" structure and accurately cut off the path of cold and heat conduction. The sophisticated internal multi-cavity design is like building an efficient "insulation cabin" for the building, which greatly improves the thermal insulation performance of the profile itself and locks in warmth from the root of the frame. Glass system: the core of constant temperature protection ● Low-E low-emissivity glass: Its surface is coated with a metal film invisible to the naked eye, which can efficiently reflect the infrared rays of indoor heating heat back, while allowing short-wave radiation in sunlight to enter, achieving "lighting but not heat", passively collecting solar heat and increasing indoor temperature. ● Hollow filled with argon gas: Double or three-layer hollow structure, and the hollow layer is filled with inert gas - argon. Argon gas has lower thermal conductivity and can significantly inhibit convective heat transfer in the hollow layer, turning the entire glass into a high-performance "transparent thermal insulation wall". Ultimate sealing: building an airtight line of defense Using EPDM automotive grade sealing tape, three or more continuous sealing layers are formed around the door and window opening sash. This rigorous system can effectively resist the infiltration pressure of outdoor cold wind and ensure that the indoor warm environment is not disturbed by external airflow. Smart integration: active temperature management This is the sublimation of the value of "intelligence": Linkage with the environment: Door and window sensors can be seamlessly connected with smart home systems. When the temperature sensor detects that the temperature difference between indoor and outdoor is too large, it can automatically remind the user to close the window; it is linked with the smart curtain to automatically close at night to form an additional insulation layer. Collaboration with equipment: Linked with air conditioning and floor heating systems, when the system confirms that the windows are closed, it will intelligently optimize the operating mode of the heating equipment to avoid empty energy consumption. It has been proven in practice that It can help save up to 30% energy. 3. More than just thermal insulation: multi-dimensional value upgrade of intelligent system doors and windows Winter insulation is a core advantage, but the value of smart system doors and windows goes far beyond that. It integrates thermal insulation, energy saving, safety and convenience to reconstruct the modern living experience: ● Energy saving and consumption reduction: Excellent thermal insulation performance can reduce heating energy consumption by 30%-50% in winter. Long-term use can significantly reduce energy expenditure, which is in line with the trend of green and low-carbon living. ● Silent and noise reduction: The sealed structure and insulating glass synchronize to achieve sound insulation effect, which can isolate outdoor wind, snow and traffic noise. The indoor noise is less than 35 decibels, creating a quiet living environment. ● Security protection: The combination of smart locks, anti-pry hardware and tempered glass, combined with a remote alarm function, can ensure home safety even when windows are opened for ventilation in winter, taking into account both thermal insulation and peace of mind. Using technology to make winter living more quality The warmth in winter comes from the ultimate pursuit of details. Intelligent system doors and windows use professional insulation technology, precise structural design and intelligent control logic to completely solve the problem of "cold entering through the window". It not only brings a constant temperature and comfortable home experience to residents, but also implements the concept of green living by saving energy and reducing consumption. Choosing a high-quality intelligent system door and window is to build a solid "warmth barrier" for your home. Let every cold winter be spent in a quiet, constant temperature, and secure environment. This is the core meaning of technology empowering life.

By 2030, the market size is expected to be Breaking through 110 billion yuan . This data fully proves the huge potential and commercial value of the smart doors and windows market. 3. Design evolution: the integration of aesthetics and functionality Contemporary intelligent system doors and windows are no longer just functional components of buildings, but have evolved into works of art that combine aesthetics and craftsmanship. Minimalist design style has become the mainstream of the market. The application of extremely narrow frames and large areas of glass optimizes lighting and field of view to the greatest extent while ensuring structural safety. Personalized color customization has also become a new trend, providing a variety of color options to meet the matching needs of different building facades and interior decoration styles.

The application of advanced technologies such as multi-cavity insulation structures, Low-E glass, and argon-filled hollow layers has greatly improved the thermal insulation performance of products; the promotion of environmentally friendly profiles and lead-free spraying processes reflects the industry's practice of green and healthy concepts. Redefining warmth with technology Driven by the two-wheel drive of technological innovation and consumption upgrading, intelligent system doors and windows are opening a new era of smart life. This is not only a product upgrade, but also a profound change in the concept of living. The home of the future will be an intelligent life form that can sense and adapt to the needs of its residents. Every smart door and window is no longer a cold building component, but a considerate life steward, using technology to redefine the beautiful relationship between people and space. This may be the meaning of the evolution of smart home - to allow innovation to truly serve the happy time of every family.

The "black technology" of smart system doors and windows always attracts attention - automatic switches, wind and rain sensors, remote control... But many people ignore that smart system doors and windows in the true modern sense are far more than gorgeous profiles and hardware. Its core "wisdom" and "performance", to a large extent, All hidden in that seemingly simple glass . Today, we will reveal the mystery of smart door and window glass and see how this "thinking" glass can reshape your home life. The cornerstone of performance: more than just two layers of glass In the context of smart system doors and windows, glass is not an isolated component, but a "core functional unit" that works in conjunction with profiles and sealing systems. It mainly solves three core problems: Thermal performance (thermal insulation), acoustic performance (sound insulation and noise reduction) and safety. Insulated glass: the “basic standard” for smart doors and windows A commonly used and practical type of glass, it consists of two or more layers of glass, with a cavity reserved in the middle and filled with dry gas. Core advantages: It has outstanding sound insulation effect (can reduce 25-40 decibels) and can isolate most traffic noise and neighborhood noise; its thermal insulation is better than single-layer glass, reducing indoor and outdoor temperature exchange. Intelligent adaptation: The weight is moderate and will not increase the load on the intelligent opening and closing system; the cavity sealing performance is good to avoid sensor failure due to moisture. Low-E insulated glass: the “optimal solution” for energy-saving parties One of the surfaces of the insulating glass is coated with a special low-emissivity coating, which is an "energy-saving upgrade" of smart doors and windows. Core advantages: It can reflect infrared rays, block external heat from entering in summer, and retain indoor heat in winter, which can reduce air conditioning energy consumption by more than 30%; it does not affect the transmission of visible light, and the room is still bright. Intelligent adaptation: Reduce glass fogging caused by indoor and outdoor temperature differences and prevent fog from affecting the sensing accuracy of smart doors and windows. Laminated glass (laminated glass): a safety-first “protective shield” It consists of two or more layers of glass sandwiched with a layer of PVB/SGP film, which will not splash even if broken. Core advantages: It has strong impact resistance and is not easily smashed. It can prevent theft and falling objects from height. After it is broken, the film will stick to the glass fragments to avoid scratches. It is especially suitable for families with elderly and children. Intelligent adaptation: The material is tough and can cooperate with intelligent security systems. If it encounters a collision, it can be linked to the door and window alarms to trigger the alarm. Strong alliance: the smart combination of 1 1>2 The performance of a single glass is limited. Real smart system doors and windows will "combine the formula" of the above glass according to your specific needs to achieve customized performance. [Silent formula] Laminated insulating glass Structure: Outer layer of laminated glass, hollow layer, inner layer of glass. Effect: The laminated layer deals with low-frequency noise (traffic), and the hollow layer deals with mid- and high-frequency noise (human voice), achieving high-efficiency sound insulation in the full frequency range. This is the "solution" for street-facing homes. [Energy-saving and comfortable formula] Low-E insulated glass (or three glass and two chambers) Structure: One piece of Low-E glass, hollow layer, one piece of ordinary glass. The upgraded version can be three pieces of glass forming two air layers. Effect: Low-E film reflects heat, and the hollow layer blocks heat conduction, providing double protection. Three glass and two cavities further improve the thermal and sound insulation limits, and are suitable for passive houses and extremely cold/hot areas that require energy saving. A complete smart door and window is the art of collaborative operation of profiles, hardware, strips and glass. This piece of glass integrated with modern material science is the intellectual core and performance cornerstone of this system. Together with other smart functions, it weaves a living dream of constant temperature, quietness, safety and energy saving. Choosing a window is choosing a way of life. Start by understanding this piece of glass and inject real wisdom and calmness into your life.

Recently, the national "Building Energy Efficiency Design Standards" ushered in a major revision, which put forward new mandatory requirements for the core indicator of the building envelope-the heat transfer coefficient K value of doors and windows: ≤1.0W/(㎡・K). This energy efficiency threshold, which can be called the "most stringent in history", not only marks the official entry of my country's building energy-saving standards into a new era, but also directly spawns a huge market for energy-saving renovation of existing buildings with a scale of up to 100 billion yuan. A building energy-saving revolution centered on "replacement of doors and windows" is sweeping across the country with rapid breadth and depth. From “insulation” to “near-zero consumption”, the strategic implications of K value ≤ 1.0 What is K value? It measures the heat transferred by doors and windows through unit area under unit time and unit temperature difference. The lower the K value, the better the thermal insulation performance of doors and windows. This standard raises the K value requirement to ≤1.0, which is a leap-forward upgrade to the original standard. This means that the insulation performance of doors and windows must be close to or even equal to that of doors and windows used in Passive Houses. In the severe cold winter in the north, it can greatly reduce the loss of indoor heat to the outside; in the hot summer, it can effectively block the intrusion of external heat, thereby achieving "warmth in winter and coolness in summer" and greatly reducing the energy consumption of building heating and cooling. This is a key step for my country to achieve its "double carbon" goal and promote the construction field to move towards ultra-low energy consumption and near-zero energy consumption. If the ordinary windows in the past are compared to a single piece of clothing, then the doors and windows that meet the new national standard K≤1.0 are a professional-grade "constant temperature down jacket", which can firmly lock the indoor temperature comfort zone and make the building truly "wear a cotton jacket". 100 billion to transform blue ocean, who is the biggest demand engine? The improvement of standards directly translates into huge momentum in the market. According to statistics, my country's existing construction area exceeds 60 billion square meters, of which more than 80% are high-energy-consuming buildings. The implementation of the new standards means that a huge existing building door and window renovation market has been instantly activated. ● Scale perspective: The market size is as high as 100 billion yuan, covering a wide range of fields from residences, public buildings to industrial plants. This is not only a product replacement, but also a whole industry chain opportunity covering testing, design, production, installation and service. ● Regional focus: North China and East China's severe cold regions account for the most demand, accounting for 43%! This region has long and cold winters, huge heating energy consumption, and the most urgent requirements for building insulation performance. Beijing, Tianjin, Hebei, Shandong, Liaoning and other places will become the core battlefields and demonstration highlands of this transformation wave. Local governments are expected to introduce corresponding supporting policies and subsidies to further accelerate market release. Technology and brand win, the door and window industry faces a big test The requirement of K value ≤ 1.0 is a technological reshuffle and industrial upgrade for the doors and windows industry. Ordinary aluminum alloy single-glass windows and even some broken-bridge aluminum windows with insufficient performance will gradually be eliminated by the market. ●Technical core: Products that meet the new standards must adopt processes such as multi-cavity structural insulation strips, three-glass and two-cavity argon-filled Low-E glass, and innovative warm edge technology. System doors and windows and passive doors and windows will become the mainstream of the market. ● Competition landscape: The market will shift from price competition to comprehensive strength competition with performance, quality and service as the core. Leading companies with strong technology research and development capabilities, mature system solutions and brand influence will gain development opportunities. Embrace change and win a green future For real estate developers, building owners and even every consumer, this is both a responsibility and a blessing. ● For developers and owners: High-standard energy-saving doors and windows should be proactively included in new construction and renovation plans. This is not only an inevitable requirement to meet regulations, but also a wise move to improve construction quality, reduce operating costs, and demonstrate social responsibility. ● For consumers: When purchasing or renovating a house, the K value of doors and windows should be taken as a key consideration. Choosing a high-performance energy-saving window means continuing to enjoy a more comfortable, healthier, and more energy-saving living environment for decades to come, as well as substantial savings on energy bills. Hundreds of billions of blue ocean insights into opportunities in the era One-window change leads to a green future A standard and an order open up not only a market, but also an era. When the "carbon footprint" of buildings is accurately measured, and when green "binding indicators" are transformed into the "certain future" of the industry, we are standing at the starting point of a profound change. The 100-billion-level transformation blue ocean is a generous opportunity given by the market, and it is also a heavy responsibility given to the industry by the times. It drives technological innovation, reshapes the industrial landscape, and ultimately points to a high-quality, more sustainable future. This is not the end, but a prelude to China’s building movement toward ultra-low energy consumption. Whoever can make the first breakthrough in this round of green racing will have the right to define and speak in the grand narrative of the future.

With the increasing number of high-rise buildings in cities, the living comfort and safety of high-rise residences have become the focus of people's attention. As an important home product that enhances the living experience, smart doors and windows must not only have convenient intelligent control functions, but their wind pressure resistance performance is also a core indicator related to residential safety. After all, high-rise residences face stronger winds and greater wind pressure. If smart doors and windows are not strong enough to withstand wind pressure, not only may problems such as door and window deformation, air leakage, and rain leakage occur, but in severe cases, it may also threaten the safety of family members. So, how should high-rise residential buildings choose smart doors and windows with wind pressure resistance? 1. First understand the “wind pressure challenges” of high-rise residential buildings before you can choose the right smart doors and windows. The core reason why high-rise residential buildings have strict requirements on the wind pressure resistance of doors and windows lies in the "positive correlation between height and wind force." According to the principles of fluid mechanics, the higher the height above the ground, the fewer obstacles the air flow will encounter, and the wind speed will increase significantly, resulting in greater wind pressure. Generally speaking, for residential buildings with more than 10 floors, the wind speed will be 30% - 50% higher than the ground level, and for high-rise buildings with more than 20 floors, the wind pressure may even reach 2 - 3 times that of the ground level. This continuous strong wind pressure will have many impacts on doors and windows: Under long-term wind pressure, smart doors and windows with weak wind pressure resistance may experience deformation of window frames and loose glass, leading to a decrease in the sealing performance of doors and windows, causing air leakage and water seepage problems. In extreme weather such as heavy rains and typhoons, if doors and windows cannot withstand strong wind pressure, there may also be safety hazards such as glass breakage and door and window sash falling off. Therefore, when choosing smart doors and windows for high-rise residences, wind pressure resistance must be given top priority, rather than simply pursuing the richness of smart functions. 2. The “core hard indicators” of wind pressure-resistant smart doors and windows are indispensable. If you want to choose wind pressure-resistant smart doors and windows suitable for high-rise residences, you can't just listen to the merchants' propaganda. You must learn to pay attention to the core technical indicators and design details of the product. Specifically, you can start from the following four aspects: (1) Look at the material: Choosing the right “skeleton” is the basis for wind pressure resistance The "skeleton" of doors and windows - profiles, directly determines the lower limit of their ability to resist wind pressure. Currently, the common smart door and window profiles on the market mainly include aluminum alloy, broken bridge aluminum, plastic steel, etc. Among them, broken bridge aluminum profiles are the first choice for high-rise residential buildings. The broken bridge aluminum profile adopts a multi-cavity structure design, and the thickness of the profile must be more than 1.4mm (it is recommended to choose a thickness of 1.6mm and above for high-rise buildings with more than 20 floors). This structure can effectively disperse wind pressure and reduce the possibility of deformation of doors and windows. At the same time, attention should be paid to the alloy composition of the profile. High-strength aluminum alloy profiles containing elements such as magnesium and silicon have higher tensile strength and yield strength and better wind pressure resistance. In contrast, ordinary plastic steel profiles have low hardness and are prone to aging and deformation when exposed to strong wind pressure for a long time. They are not suitable for super high-rise residential buildings with more than 30 floors. (2) Look at the glass: "Safety shield" needs to take into account both wind pressure resistance and explosion protection Glass is an important component for smart doors and windows to withstand wind pressure. When choosing smart doors and windows for high-rise residences, the configuration of the glass is particularly critical. It is recommended to give priority to double-layer insulated tempered glass or even triple-layer insulated tempered glass (above the 30th floor or in areas prone to typhoons). The impact strength of tempered glass is 3-5 times that of ordinary glass. It can effectively withstand the impact of strong wind pressure. Even if it breaks, it will form small particles without sharp angles, reducing safety risks. In addition, the sealing performance of insulating glass is also very important. The insulating glass adopts a double-pass sealing design. The first pass is sealed with butyl glue, and the second pass is sealed with polysulfide glue or structural glue. This can effectively prevent air from entering the hollow layer, avoid fogging of the glass due to changes in air pressure, and also enhance the overall wind pressure resistance of the glass. (3) Look at the structural design: details determine the “upper limit” of wind pressure resistance The impact of the structural design of smart doors and windows on their wind pressure resistance cannot be ignored. The following details need to be focused on: The connection method between the window frame and the wall: Smart doors and windows will be fixed to the wall using expansion bolts, and the distance between the fixed points shall not exceed 600mm. At the same time, waterproof insulation mortar or foam glue is filled between the window frame and the wall, which can not only enhance the stability of the connection between the door and window and the wall, but also prevent the door and window from being displaced due to wind pressure. Sealing structure of door and window sash: It is recommended to choose smart doors and windows with multi-layer sealing design, such as three or four layers of sealing tape. The material of the tape is preferably EPDM tape (anti-aging, good elasticity), which can effectively prevent strong wind from penetrating through the gaps. It can also improve the wind pressure resistance of doors and windows and prevent door and window sash from shaking under the action of wind pressure. Stability of the drive system: The opening and closing of smart doors and windows depends on the drive system. When choosing a high-rise residence, it is necessary to ensure that the drive motor has sufficient torque and can operate stably in a strong wind pressure environment. At the same time, the drive system should have an overload protection function to avoid motor damage due to excessive wind pressure. (4) Look at testing and certification: you will feel more at ease if you look for authoritative standards When choosing smart doors and windows for high-rise residences, be sure to check whether the product has authoritative wind pressure resistance testing certification. The current domestic testing standard for the wind pressure resistance of doors and windows is GB/T 7106-2019 "Classification and Testing Methods for Airtightness, Watertightness, and Wind Pressure Resistance of Exterior Building Doors and Windows". This standard divides the wind pressure resistance of doors and windows into levels 1 to 9. It is recommended for high-rise residences to choose products with a wind pressure resistance performance level of no less than level 6 (level 6 can withstand wind pressure values ≥3.0kPa, suitable for 20-30-story residences), 30 For super-high-rise residential buildings above one storey, it is recommended to choose products of level 7 and above (≥3.5kPa). At the same time, you can also check whether the product has passed China's compulsory product certification (3C certification), especially the tempered glass part, which must have the 3C certification mark to ensure that product quality meets safety standards.
